Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to prevent electrical shock.
Raise the vehicle securely using jack stands if necessary.

2. Inspect and Repair Wiring

Sub-steps:
1. Locate the transmission range sensor and its wiring harness.
2. Visually inspect the wiring for frays, breaks, or corrosion.
3. If damage is found, repair or replace the damaged wires using appropriate connectors and heat shrink tubing.

3. Replace the Transmission Range Sensor

Tools Required:
- Socket set
- Torque wrench
- Screwdriver set
Sub-steps:
1. Remove the bolts securing the transmission range sensor using a socket wrench.
2. Carefully disconnect the electrical connector from the sensor.
3. Remove the old sensor and clean the mounting surface.
4. Install the new sensor by reversing the removal steps.
5. Torque the mounting bolts to the manufacturer's specifications (typically around 8-10 ft-lbs).

4. Reconnect Battery and Test

Sub-steps:
1. Reconnect the negative battery terminal.
2. Start the vehicle and allow it to idle for a few moments.
3. Shift through all gears to ensure proper engagement.

5. Clear Codes

Use an OBD-II scanner to erase any stored trouble codes and check for reoccurrence.
